20090182556 | PITCH ESTIMATION AND MARKING OF A SIGNAL REPRESENTING SPEECH - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, a method of processing a signal representing speech can comprise receiving a frame of the signal representing speech, classifying the frame as a voiced frame, and parsing the voiced frame into one or more regions based on occurrence of one or more events within the voiced frame. For example, the one or more events can comprise one or more glottal pulses. The one or more regions may collectively represent less than all of the voiced frame. | 07-16-2009 |
20090271183 | PRODUCING TIME UNIFORM FEATURE VECTORS - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, processing a signal representing speech can comprise receiving a frame of the signal representing speech, the frame comprising a voiced frame. One or more cords can be extracted from the voiced frame based on occurrence of one or more events within the frame. For example, the one or more events comprise one or more glottal pulses. The one or more cords can collectively comprise less than all of the frame. The one or more cords can be normalized on a time basis. For example, each of the one or more cords can begin with onset of a glottal pulse and extend to a point prior to an onset of neighboring glottal pulse but may exclude a portion of the frame prior to the onset of the neighboring glottal pulse. | 10-29-2009 |
20090271196 | CLASSIFYING PORTIONS OF A SIGNAL REPRESENTING SPEECH - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, processing a signal representing speech can comprise receiving a frame of the signal representing speech. The frame can be classified as unvoiced or voiced based on occurrence of one or more events within the frame. For example, the one or more events can comprise one or more glottal pulses. In response to classifying the frame as voiced, the frame can be processed. | 10-29-2009 |
20090271197 | IDENTIFYING FEATURES IN A PORTION OF A SIGNAL REPRESENTING SPEECH - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, processing a signal representing speech can comprise receiving a region of the signal representing speech. The region can comprise a portion of a frame of the signal representing speech classified as a voiced frame. The region can be marked based on one or more pitch estimates for the region. A cord can be identified within the region based on occurrence of one or more events within the region of the signal. For example, the one or more events can comprise one or more glottal pulses. In such cases, cord can begin with onset of a first glottal pulse and extend to a point prior to an onset of a second glottal pulse. The cord may exclude a portion of the region of the signal prior to the onset of the second glottal pulse. | 10-29-2009 |
20090271198 | PRODUCING PHONITOS BASED ON FEATURE VECTORS - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, processing a signal representing speech can comprise receiving a first frame of the signal, the first frame comprising a voiced frame. One or more cords can be extracted from the voiced frame based on occurrence of one or more events within the frame. For example, the one or more events can comprise one or more glottal pulses. The one or more cords can collectively comprise less than all of the frame. For example, each of the cords can begin with onset of a glottal pulse and extend to a point prior to an onset of neighboring glottal pulse but may exclude a portion of the frame prior to the onset of the neighboring glottal pulse. A phoneme for the voiced frame can be determined based on at least one of the extracted cords. | 10-29-2009 |
20130046533 | IDENTIFYING FEATURES IN A PORTION OF A SIGNAL REPRESENTING SPEECH - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, processing a signal representing speech can comprise receiving a region of the signal representing speech. The region can comprise a portion of a frame of the signal representing speech classified as a voiced frame. The region can be marked based on one or more pitch estimates for the region. A cord can be identified within the region based on occurrence of one or more events within the region of the signal. For example, the one or more events can comprise one or more glottal pulses. In such cases, cord can begin with onset of a first glottal pulse and extend to a point prior to an onset of a second glottal pulse. The cord may exclude a portion of the region of the signal prior to the onset of the second glottal pulse. | 02-21-2013 |
